Ok so we launched on 10.10.10 to coincide with the release of 11.10. The 12.10 release is on 18 October, so if we run a contest from 10 October (our 2 year anniversary) to 24 October it gives us almost exactly one week before and one week after the release of 12.10's release10, which means the timing is pretty excellent to prep for the incoming onslaught and subsequent follow up.
